Hot Water Heaters by Bosch

The Bosch Greentherm models are now equipped with an automated and fully modulating bypass for unsurpassed DHW temperature stability. All Greentherm models feature condensing technology for improved efficiency. By capturing the latent heat of the flue gases the efficiency of the water heater is boosted by approximately 10%.

Operating with an energy factor up to 0.94 the Greentherm models economically provide domestic hot water on demand. Our Tankless water heaters are wall-mounted to save space and the technology only uses gas to heat the water when there is a demand. The Greentherm’s innovative features ensure maximum performance to provide virtually endless hot water.
